Specification of Letters Patent.

Patented Oct. 6, 1914.

Application filed April 21, 1914. Serial No. 833,473.

Y '0 (ZZZ whom it may concern Be it known that I, JOHN M. FISCHER, a citizen of the United States, residing at De Soto, in the county of Jefferson and State of Missouri, have invented certain new and useful Improvements in lVhiflletree-l-looks, of which the following is a specification.

My invention relates to whi'lfle tree hooks and more particularly to a device attached to a whi'lile tree for removably holding a trace thereon.

The primary object of my invention is to provide an improved means for mounting a trace fastener on a whiflle tree.

Another object of my inventionis to provide an improved means for mounting the elastic element for removably holding the guarding member in position.

A further object of my invention is to provide an improved ferrule beingcast in one piece and having a'means formed thereon for recei *ing the elastic element and the trace.

A still further object of my invention is to provide an improved device of the character described that is simple in construction, eflicient in operation and one that can be manufactured and placed on the market at a minimum cost.

Other objects as well as the nature characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawings :-Figure 1 is a top plan view of my invention; Fig. 2 is a longitudinal sectional view taken on the line 22 of Fig. 1 in the direction in which the arrow points; Fig. 3 is a top plan view of my improved ferrule applied to a portion of the whiiile tree.

Referring more particularly to the drawings in which similar reference numerals designate corresponding parts throughout the different views I provide a whifile tree 1 having a reduced end 2 the latter having mounted thereon by means of rivets 3 and 4 my improved ferrule 5.

The ferrule has the outer end thereof reduced to form a substantially flat neck 6, the outer edge of which has formed thereon an enlarged head 7 which has one end thereof tapered as at 8 to facilitate the mounting of a trace 9 thereon and is further provided with an opening 10 extending therethrough for a purpose to be hereinafterdescribed. Extending laterally from diametrically opposite points and formed integral with the outer surface of the ferrule at points approximately intermediate the ends of the ferrule are studs 11 which have pivotally mounted thereabouta yoke 12.

The yoke 12 is formed preferably of resilient material and has its outer ends thereof slightly enlarged and provided with openings 13 for removable engagement with the studs 11. Rigidly secured to the under surface of the yoke approximately interme diate the ends of the same by means of a suitable fastening device, preferably a rivet 14f, is a lever 15, the outer end of which is curved slightly upward as at 16 to form a substantial finger piece for a purpose to be hereinafter referred to and is provided adjacent the outer edge thereof with an opening 17 in which is mounted the reduced end of a guarding pin 18. The guarding pin 18 depends from the lever and has its lower reduced end removably engaged in the open ing for. retaining the trace 9 upon the neck 6.

-For the purpose of holding the pin 18 in engagement with the opening 10, I have provided the upper surface of the ferrule 5 about the opening in which the pin i is engaged with a longitudinal recess 10 which is slightly slanted toward the outer end of the ferrule and has secured in the same by means of the pin 4 a leaf spring 20, the free end of which extends upwardly and is slidingly engaged in the longitudinal recess 21 in the opposite end of the lever which forms a handle member for facilitating the operation of the pin 18. The recess 21 being directly above the spring cooperates with the spring and prevents any lateral movement of the lever 1.5 and greatly facilitates the operation of the pin 18 within the opening 10.

The operation of my device is as follows: \Vhen it is desired to place the trace 9 upon the neck 6 all that is necessary to do is for the user to place one hand (not shown) upon the inner or handle portion of the lever 15 and press the same downwardly against the tension of the spring 20 and thus remove the pin 18 from engagement with the opening 10 in the head 7. The opening in the trace is then placedv about the tapered portion 8 of the head and slid into position upon the neck 6. of the lever 15 then released and the spring causes the pin 18 to again engage the opening 10. To remove the trace from pcsitirn on the neck it is obvious that this operal ion need only be reversed. If it is desired to remove the trace with one hand. all that is necessary is for the user to place one of his thumbs (not shown) upon the under surface of the curved portion 16 of the lever and press the same upwardly. This causes the handle portion of the lever 21 to bear against and press the spring downwaiv'lly It can be easily seen that the user while holding the forward end of the lever in an upward position the trace 9 can easily be removed by the fingers of the hand which he is using to hold the forward end in this position.

l rrm the above description taken in connection with the accompanying drawings it can be easily seen. that I may form the yoke 19', the lever 15 and the pin 18 in one piece in order to reduce the 0 st of manufacture, however, the form shown is the preferred form. T he reason for this is because in the case that only certain parts should become broken, these parts could be obtained at a very low price and readily connected to the original parts.

ll desire it to be understood that great stress be laid upon the manner in which. the spring QO'is mounted. The pin t by which the spring is secured serves the dual purpose of securing the spring to the ferrule in place on the end of the Whittle tree. Again, the free end of the spring co-acting with the recess 2 in the handle portion of the lover te to maintain the pin 18 in a position d *ectly above the opening 10 and greatly facilitates the operation of the device.

From the above vdescription taken in connection with the accompanying drawings it can be easily seen that I have provided a device that is simple in construction containing but a few simple parts that can be easily and cheaply manufactured and waen manufactured can be placed on the market and sold at a minimum cost.

lit will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the ad vantages of my invention.

Having thus fully described my invention,

The handle portion what I claim as new and desire to secure by Letters Patent is 1. In a whill'le tree hook, the combination with a ferrule having a neck and a head formed thereon, and a yoke pivotally connected to the ferrule, a lever secured intermediate its ends to said yoke, a guarding pin depending from the forward end of the lever, the rear end of the lever constituting a handle and having the under surface thereof provided with a longitudinal recess, a leaf spring carried by the ferrule the free end of the spring bearing against the recess in the handle portion of the lever for maintaining the pin in a position above the head.

2. In a Whittle tree hook, the combination with a ferrule having a neck and a head formed thereon, said head having an opening therein, studs projecting from the opposite sides of the ferrule, of a spring yoke detachably connected about the studs, a lever carried by the yoke, a guarding pin depending from the forward end of the lever for removable engagement with the opening, the rear end of the lever constituting handle portion and having its under surface provided with a longitudinal recess, a leaf spring, one end of said spring being secured to the ferrule, and the opposite end of the spring bearing against the longitudinal re cess in the handle portion of the lever for maintaining the pin in engagement with the opening and preventing lateral moven'ient of the same.

In a whi'l'lle tree hook, the combination with a ferrule having a neck and a head formed thereon, said head having an open ing therein, said ferrule further provided with a longitudinal groove adjacent the free end thereof, and means for fastening the ferrule to the whii'lle tree, of a lever pivotally connected to the ferrule, a guarding pin carried by the forward end of the lever for engagementwith the opening in the head, the rear portion of the lever having its under surface provided with a longitudinal recess, a leaf spring disposed in the recess in the ferrule and secured by the fastening means of the ferrule, the free end of the spring bearing against and slidably arranged within the recess in the lever for maintaining the pin in engagement with the opening and for preventing lateral movement of the parts.

In testimony whereof I aliix my si nature in presence of two witnesses.
